Answer:
See Explanation
Step-by-step explanation:
The question is incomplete. I will assume the function is:

Required
Determine the rate of decay
In an exponential function
,
The decay rate of the function is calculated as:

By comparison:

So, the equation becomes:

Make r the subject


<em>The rate of decay is 0.14</em>
Answer:
angle Y = 90 degrees
Step-by-step explanation:
Since it is stated that angle x forms a straight line with the 50 and 50 degree angles, and that angle x is vertical to angle y, we can do 40+50+y=180 to find angle Y.
